SOFIA made observations of ionized carbon (CII) at the center of IC 342 galaxy using the GREAT (German REceiver for Astronomy at Terahertz frequencies) far-IR spectrometer in September 2011 as part of the mission’s Early Science program.

SOFIA/FORCAST images of the H II (ionized hydrogen) complex G0.02-0.07 resolved a string of three compact HII regions (labeled A, B, and C in Figure 1) plus two new infrared sources designated FIRS 1 and 2 (Figures 1 and 2). G0.02-0.07 is located in the Sagittarius A (Sgr A) region, 6 pc (20 light years) from our line of sight to the center of the Milky Way Galaxy. The Galactic Center includes a hot, turbulent interstellar medium, cloud-cloud collisions, stellar winds, and supernova shocks.
